David Cameron: 'These strikes are wrong'

David Cameron has told public sector workers unhappy about their pensions that striking would be "wrong - for you, for the people you serve, for the good of the country".

The PM said reform was "essential" to stop the pensions system "going broke".

And, he added, the changes were fair to both workers and the taxpayer.

Up to 750,000 teachers and civil servants are set to strike saying that the government's plans will mean them working longer and paying more.
